The mass spectrum of CH 3 CH 2 CH 2 COOD shows no observable loss of C 2 H 3 D. This indicates for this compound that either the McLafferty rearrangement is concerted, or that the second step (olefin loss) is very fast in comparison to the reverse transfer of hydrogen back to the methylene radical.
